Powder thickness in closed casting powder

Measure the true steel level in closed casting

Precise knowledge of the powder layer thickness enables more accurate monitoring of the real liquid steel level in closed systems. This, in turn, allows for the exact dosing of powder via an automatic feeder, maintaining a consistent powder layer and reducing the need for manual intervention in hazardous working areas. The detector additionally uses silicon photomultiplier (SiPM) technology to ensure maximum robustness against
interference from nearby electromagnetic stirrers and brakes, while providing outstanding temperature stability.

Radiometric measurement for steel and powder levels

Redefining industry standards

Berthold Technologies, in collaboration with SMS Concast, has developed the state-of-the-art LB 6755 CONGAUGE detector. By combining ten scintillation crystals with an advanced software algorithm, the device can accurately distinguish the true casting level of molten steel from the thickness of the casting powder layer – all within a single unit. The separate output of the powder signal enables precise monitoring of the powder thickness and an evenly dosing of the powder.

The precise monitoring and control of casting powder thickness is beneficial for customers in the following ways:

✦ Reduced number of breakouts
✦ High stability of mold level accuracy
✦ Improved steel quality level
✦ Process automation by integration of automated powder feeder

Determining the powder thickness

Discover how Berthold’s advanced radiometric solution measures the steel level and powder thickness in real time. Uncontrolled powder layers can distort meniscus readings and compromise quality. Learn how our innovative detector accurately determines both simultaneously. Our LB 6755 CONGAUGE uses a crystal array and smart algorithms to stabilize mould level and powder thickness – improving quality and reducing breakouts.
